Suspensful sci fi/horror unencumbered by a romantic subplot. It starrs Brian Donlevy supported by a professional all-British (except for Margia Dean) cast. Crisply directed by Val Guest with an above average screenplay and good production values. An infuential classic that's definitely worth a look if you haven't seen it and again if you have. Followed by "Quatermass 2" in 1957, "Quatermass and the Pit" in 1958 and "Quatermass" in 1979.
a.k.a. "The Quatermass Xperiment" (UK) and "The Quatermass Experiment" (US)
CAST NOTE: Jane Asher (little girl playing with a doll) grew up to become Paul MaCartney's ex-fiancee.
